The place and role of historical facts in the process of cognition is determined by the fact that only on the basis of these “building blocks” can hypotheses be put forward and theories built. There is no single definition of a historical fact. The most common interpretations of the term “historical fact” are:
- it is an objective event or phenomenon of the past;
- these are traces of the past, i.e. images that are captured in historical documents.
Many scientists (A.P. Pronshtein, I.N. Danilevsky, M.A. Varshavchik) identified three categories of historical facts: objectively existing facts of reality, located within a certain spatio-temporal framework and possessing materiality ( historical events, phenomena and processes as such); facts reflected in sources, information about the event; " scientific facts", obtained and described by the historian.
In the interpretation of M.A. Barga, the concept of “historical fact” has several meanings. Firstly, a historical fact as a fragment of historical reality, which has “chronological completeness and ontological inexhaustibility.” Secondly, “source message”; thirdly, a “scientific-historical fact” - in its “cognitive incompleteness, in content variability, cumulativeness, ability for endless enrichment and development” together with the development of “historical science” itself.
A scientific-historical fact is a historical fact that has become the object of activity of a scientist historian; the result of inference based on traces left by the past. These facts are always subjective and reflect the position of the scientist, his level of qualifications and education. IN academic subject most often presented scientifically historical facts, which are described, systematized and explained. Any historical fact can contain the general, the universal, the individual. Taking into account this specificity, in the methodology of teaching history, three groups of facts are conventionally distinguished: fact - event - characterizing the unique, inimitable; fact - phenomenon - reflecting the typical, general; fact - processes - determining the universal. These facts have undergone logical processing and are presented in logical forms: representations (images) contain characteristics of the external side in the form of a description; concepts, ideas, theories that characterize the essence and provide an explanation of the historical past. Facts-processes are presented by description, explanation, evaluation.
Every year in May, Mother's Day is celebrated all over the world. On this day, mothers and pregnant women are congratulated and given gifts. Motherhood is an amazing condition, but even women themselves do not know some facts about it:
- The word “mother” sounds approximately the same in all languages: Russian, Chinese and Spanish children call their mother “mama”, English and German children call their mother “mom”. And the secret is simple: the children themselves came up with this word. One of the first syllables that a child utters is “ma”, and it determined the name of the most important person in the life of each of us.
- A woman carries a child for nine months, he is born, the umbilical cord is cut, but his connection with his mother does not end there. During pregnancy, mother and baby exchange cells through the placenta, and these cells sometimes remain in the woman’s body for a very long time.
- Pregnancy causes changes in a woman's brain.
- A child’s successful personal life depends on how close his relationship with his mother was. Scientists believe that it is the mother who instills in the child the ability to love and feel, which helps him build happy relationships with the opposite sex.
- Mothers feel if something happened to the child, even if the latter is already an adult, accomplished person.
- Children know their mother's voice even before they are born. Scientists have conducted a number of studies, which have revealed that the child in the womb reacts to the mother’s voice and does not react at all to outside voices.
